JAMES ROTHSOHILD, OF NE\V YORK, N. Y.

JEWELRY.

SPECIFICATION forming part of Letters Patent No. 451,661, dated May 5, 1891.

Application filed January 6, 1891, Serial No. 376,851. (No model.)

To all whom it may concern.-

Be it known that I, JAMES ROTHSCHILD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Jewelry; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a bracelet adapted to be enlarged in order to be passed over the hand and reduced in circumference when encircling the wrist, and means to maintain the bracelet at a given size when adjusted in place upon the person.

My invention is hereinafter fully described, illustrated in the drawings, and specifically pointed out in the claims.

Referring to the accompanying drawings, wherein like letters of reference point out similar parts 011 each figure, Figure 1 is a perspective view of a braceletembodying my invention, showing in dotted lines the movable band completely extended, also showing in dotted lines the lock-handle lifted up. Fig. 2 is a sectional View of a portion of the bracelet and sliding band. Fig. 3 is a plan view of a portion of the blank sliding band.

The main member of the bracelet consists of a hollow section A, having upper plate a, ornamented in any desired style. Said upper plate may have a plain surface, as shown in the drawings, or be corrugated, embossed, or have anydesired ornamental configurations. In parallel alignment with said upper plate is an under plate a, the two being connected bysides a thus forming a box-section A,which for practical purposes should be about the length to embrace and reach over the upper portion of a wrist.

B is an extensible band, which is permanently secured at one end within the section A by soldering or riveting, its other end being loosely inserted into the opposite end of the box, through and within which it is adapted to slide to and fro, whereby, as will be readily understood, the circumferential dimension of the bracelet can be regulated at will. The band can be extended to the extent shown in dotted lines, Fig. 1. It can then be slid within the section A until it assumes the size and shape shown in full lines, although any intermediate size can be attained by introduction of only a portion of the band B within the section A, and it can be thereat held in place by means presently pointed out. The free end of the band B is preferably supplied with detents of any. suitable form. In Fig.3 the free end of the band is shown as cut into at each side, to enable portions thereof to be upturned and compose a limiting-stop, consisting of upturned detents b b, but I do not confine myself to this special form of limiting-stop, as it is obvious various analogous mechanical devices can be substituted therefor and be within the scope and purview of my invention.

0 is a cam, pivoted within and near one end of the section A, having an arm 0 projecting outwardly, as plainly seen in the drawings. WVhen said cam is in the position shown in Fig. 2, the band B will be free to slide backward and forward within the section A, its outward progress being limited by contact of detents b b, which prevent its passage beyond the cam. W'hen, however, the arm 0 is turned downwardly upon the upper surface of the section A, said cam will forcibly impinge against the band B and securely hold it Within the tubular section, whereby the bracelet will be maintained of any required circumferential dimensions. By simply lifting up the cam-handle (see dotted lines, Fig. 1) the cam will assume the position shown in Fig. 2, releasing its pressure from the band B, which willbe thus free to be extended its full length until stopped by contact of its limiting detents with the cam G.

The section A is shown in the drawings as rectangular in cross-section, but it may be spherical, arched, or of any desired shape, as taste or convenience may dictate, and the band B can be coincidently shaped to pass within a tubular section of any conformation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is"

l. Abracelet having a main tubular section A, an extensible band B, permanently connected to said section at one end, its opposite end provided with terminal limiting-detents Z) 12, beinginserted within the main section, in

connected to one end of the main section, its opposite end, provided with limiting-stops,

being loosely inserted within said tubular 15 section and free to travel therein, substantially as described.

In testimony that I claim the invention above set forth I ai'ilx my signature in presence of two witnesses.
